Abstract
Description
Title of the invention: FINISHING ELEMENT FOR A PART OF A WALL Technical field
[0001] The invention relates to a finishing element for a wall part, in particular a finishing element for a reveal, a column side, a wall or a ceiling. More specifically, the element is a plasterboard with an integrated micro-mesh profile for finishing a plasterboard wall or for finishing a wall with thin plaster. In a second aspect, the invention also relates to a method for manufacturing the element.
[0002] THE STATE OF THE ART
[0003] Reveal plates are essential construction elements used to finish the transition between the window or door frame and the wall. Traditionally, splays are finished using a plaster. When applying the plaster, standard profiles are used on the transition between two surfaces. The profiles create straight, clean lines, protect vulnerable corners, and reinforce the plaster so that it is less likely to crack or split. However, applying profiles is a time-consuming and laborious process. In addition, windows must be covered with tape, as the plaster is spread along the window. This method also makes it more difficult to achieve a flat end result.
[0004] BE1025362B1 offers a solution to laborious profiling by describing plates of Plasterboard with an integrated plasterboard profile. These prefabricated plasterboards with integrated corner profiles can be easily installed by a plasterer or DIY enthusiast. Since the reveals no longer need to be plastered, the windows no longer need to be taped, saving labor and materials. The integrated plasterboard profile has two legs or flanges and a corner edge, and is symmetrical in the transverse direction. The profile's flanges contain openings that are identical in number and position on both flanges, so the integrated plasterboard profile is also symmetrical in the longitudinal direction of the plasterboard. The profile contains relatively few openings per cm2, which increases its robustness. The profile is designed to connect a plasterboard to a wall to be plastered. The corner edge of the profile projects 7 mm beyond the plane defined by the flange that connects it to the wall to be plastered.A layer of approximately 7mm of wet plaster is then applied to the wall, also known as plastering, using the corner edge of the built-in profile as a guide for application. the coating.
[0005] One of the problems is that due to the thickness of the corner profile, the element cannot be used for applying thin plaster or for finishing a wall to which a plasterboard is fixed.
[0006] The object of the present invention is to provide a solution to this problem by developing a finishing profile comprising two flanges and a corner edge, in which the corner edge projects by at most 3 mm beyond the plane defined by one of the two flanges. The finishing profile of the present invention is further asymmetrical in the longitudinal direction due to a different number of gripping openings in the two flanges. The profile comprises a robust leg or flange without openings or with a limited number of openings, optimized for bonding in plasterboard, and a leg made of a fine micro-mesh optimized for a thin (plaster) finish. For a perfect finish, the wall or plasterboard to be finished to which the element of the present invention is connected must be finished with one or more finishing layers only over a width of approximately 35 to 45 cm from the corner edge of the integrated profile.The final finishing layer has a thickness of up to 3 mm closest to the corner profile and flattens out as the corner profile is approached. This contrasts with the profile described in BE1025362B1, where a 7 mm thick plaster is required over the entire wall to complete the finish. Furthermore, thanks to the present invention, the element with integrated profile can also be used for finishing a wall section made of plasterboard, since plasterboard is compatible with thin filling and finishing layers, but not with wet plaster.
[0007] In summary, thanks to the new profile of the splay, it is possible to use it for connection to plasterboard, among other things, while applying only a thin finishing layer, which allows significant savings in terms of material and labor costs. In addition, the installation time of the splays can be reduced, which improves the efficiency of construction projects. Summary of the invention
[0008] To this end, the invention relates to a finishing element for a wall part, characterized in that the element comprises a plasterboard in the form of a strip which is provided on at least one longitudinal edge with an accessory for creating an angle to which, on the one hand, the board and, on the other hand, a finishing layer can then be connected, the accessory being provided with an angular profile composed of an angle edge and two flanges, a first flange being fixed in the board and a second flange, more particularly a fixing and / or attachment flange, extending in a manner angular to the plate, the edge not extending more than 3 mm beyond the plane defined by the second flange.
[0009] Therefore, it is not necessary to completely cover the surface on which the second flange is fixed with, for example, a 7 mm thick plaster, as is the case in the current state of the art, but it is sufficient to apply a maximum of 3 mm of finishing, for example, a thin plaster on the wall or on the plasterboards that constitute the wall connected to the second flange. When finishing a plasterboard wall, the finishing layer with a maximum thickness of 3 mm is applied using fillers and finishing agents traditionally used for finishing plasterboards. The element of the invention makes it possible to obtain a perfect finish if the final finishing layer is only applied over a width of approximately 35 to 45 cm measured from the accessory.
[0010] In a specific embodiment, the corner profile is asymmetrical with respect to the longitudinal direction. More precisely, the asymmetry is achieved because the two flanges are provided with a different number of gripping openings per unit area.
[0011] The purpose of the first flange is to securely anchor the corner profile in the plate. To achieve this, the first flange has no or few larger openings, for example at most 1 gripping opening per cm2. The free gripping openings in the second flange are intended to achieve a firm connection between the element on the one hand and the finishing layer on the other hand with a thin finishing layer, and to enable mechanical attachment of the profile to the wall to be finished, for example by stapling. For this purpose, a large number of small openings are provided in the second flange, for example at least 5 gripping openings per cm2. This contrasts with the original design, where a panel was provided with an integrated corner profile that was symmetrical in the longitudinal direction and had the same number of gripping openings per unit area in both flanges.
[0012] In another embodiment, the invention relates to a device which, on the one hand, during manufacturing, promotes the flow of the glue through the gripping openings, thereby reducing the mobility of the corner profile in the board, or the risk of the corner profile coming off the board, and, on the other hand, during finishing, ensures that the adhesion of the corner profile to the plaster and the glue is uniform, so that a balanced connection without weak points can be achieved.
[0013] In another embodiment, the element of the invention reinforces the rigidity of the plate at the end of the slot and thus remedies the frequent cracking or breaking of the traditional design at this location.
[0014] In another aspect, the present invention relates to a method of manufacturing such an element, characterized in that it consists of forming a plasterboard in the shape of strip; inserting a slot in at least one longitudinal edge of the plate; and inserting and fixing in this slot with a flange an angle profile as described herein.
[0015] In yet another aspect, the present invention relates to a use of the element as described above, characterized in that this method consists of putting the element in length and width; fixing said element to the unfinished splay; and finishing the part of wall to which the second flange of the accessory connects, the aforementioned element, more particularly the accessory belonging to it, being used as a guide for the finishing.
[0016] In a final aspect, the present invention relates to a corner profile comprising two flanges provided with gripping openings, wherein the corner profile is asymmetrical in the longitudinal direction due to the presence of a different number of gripping openings per unit area in the two flanges, and wherein the corner profile is configured such that the shortest distance between the corner edge of the corner profile and the plane defined by the second flange is at most 3 mm. In another embodiment, a first flange comprises on average at most 1 gripping opening per cm2 and a second flange comprises on average at least 5 gripping openings per cm2. DETAILED DESCRIPTION

However, this should be understood to mean that the value of the quantity where the term "about" or "around" is used is itself specifically disclosed.
[0019] The terms "comprise", "comprising", "contain", "containing", "comprise", "comprising", "include" and "including" are synonymous and are inclusive or open terms indicating the presence of the following, and do not exclude the presence of other components, features, elements, members, steps, known from the prior art or described therein.
[0020] Quoting numerical intervals by endpoints includes all integers, fractions, and / or real numbers between the endpoints, including those endpoints.
[0021] The term "reveal" refers to the interior surface of the material surrounding an opening (e.g., a window or door).
[0022] In this document, the term "corner profile" describes an element composed of two legs which form an angle or corner edge between them, when this element has only one cross-section, which is small compared to the length of the element.
[0023] The term "flange" (plural "flanges") is used herein to describe a leg of the aforementioned corner profile. A distinction is made here between the "first flange", the leg of the corner profile located or to be located in the plasterboard, and the "second flange", the leg of the corner profile located or to be located in the finishing layer.
[0024] The term "longitudinal edge" is used herein to describe the thin side edges of the strip-shaped plasterboard. Preferably, this term is used to describe the thin side edges along the length of the strip-shaped plasterboard.
[0025] In a first aspect, the invention relates to an accessory, also called an angle profile, for finishing corners such as the transition between a profile and a wall perpendicular to the latter. Angle profiles provide strength and support for plastering work and are indispensable in the construction sector. In the first aspect, the angle profile is preferably made of stainless and / or galvanized steel or aluminum, preferably with a thickness of about 0.5 mm, since these metals are characterized by high corrosion resistance, which allows for a durable angle profile. In another embodiment, the angle profile is made of plastic. The angle profile of the invention is composed of two flanges (15, 16) with a length preferably between 1.5 and 4 cm. In a specific embodiment, the angle profile is asymmetrical along the bisector of the angle of the angle profile.Preferably, the first flange (15) applied in the slot of a plasterboard has a length of 1.5 to 2.5 cm. In a specific embodiment, the first flange (15) preferably has a length of 1.7 to 2.2 cm or 1.8 to 2 cm or about 1.9 cm. Preferably, the second flange (16) has a length of 2.5 to 4 cm. In a particular embodiment, the second flange (16) preferably has a length of 2.8 to 3.8 cm or 3 to 3.5 cm or about 3.1 cm or about 3.2 cm. In a particular embodiment, the second flange (16) is longer than the first flange (15). Therefore, in this particular embodiment, the corner profile (11) is asymmetrical in a cross-sectional view.
[0026] In another embodiment, the corner profile (11) is asymmetrical in cross-section in that the corner edge (17) extends further from the plane defined by the first flange (15) than from the plane defined by the second flange (16), or in other words in that the distance of the corner edge (17) perpendicular to the plane defined by the first flange (15) is greater than the distance of the corner edge (17) perpendicular to the plane defined by the second flange (16).
[0027] In another embodiment, the accessory is configured such that the second flange (16) protrudes by at most 4 mm, at most 3.5 mm, at most 3 mm, at most 2.5 mm, at most 2 mm, at most 1.8 mm or about 1.6 mm relative to the wall (wall 7 or plasterboard 24) perpendicular to the splay on which the flange is fixed or such that the distance between the second flange (16) and the wall (plasterboard 24 or wall 7) perpendicular to the splay on which the flange is fixed is at most 4 mm, at most 3.5 mm, at most 3 mm, at most 2.5 mm, at most 2 mm or at most 1.8 mm or about 1.6 mm. To do this, the part (17) defining the corner edge of the accessory protrudes by at most 4 mm, at most 3.5 mm, at most 3 mm, at most 2.5 mm, at most 2 mm, or at most 1.8 mm or approximately 1.6 mm from the plane defined by the second flange (16).Thanks to the very fine mesh gripping openings of the second flange, after the finishing layer has been spread and hardened on the aforementioned second flange, a solid connection is created between the element on the one hand and the finish on the other hand. If the second flange protrudes by no more than 3 mm from the board or the wall placed perpendicular to the element, only 3 mm of finishing plaster need be applied because the corner edge (17) of the corner profile serves as a guide for applying the finishing plaster. Furthermore, if the wall consists of plasterboard, a perfect wall finish can be achieved if the finishing layer is applied over a width of approximately 10 to 50 cm from the plasterboard (24) to which the second flange (16) connects, counting from the corner profile.If the previous design described in BE1025362B1 is used, the wall to which the second flange connects must be completely covered with a plaster thickness of approximately 7 mm. In other words, the advantage of the design described here is that it allows for significant savings in material and labor costs and for finishing structures made of plasterboard.
[0028] The flanges (15, 16) are slightly bent inwards along their upper edge and are provided with gripping openings centered on the flanges, uniformly distributed, the flanges (15, 16) having a different number of gripping openings per unit area. The corner profile is thus asymmetrical in the longitudinal direction. The first flange (15) has no perforations or a series of large perforations or gripping openings (21), while the second flange (16) has a series of small perforations or gripping openings (22). The number of gripping openings per unit area in the second flange (16) is at least twice the number of gripping openings per unit area in the first flange (15).
[0029] In a specific embodiment, all gripping openings of a flange are of the same size. The size of the gripping openings (21) of the first flange (15) is at least twice that of the gripping openings (22) of the second flange (16). Due to the absence of perforations in the first flange (15) or the presence of a limited number of larger perforations in the first flange (15), the corner profile is very well anchored in the plasterboard and can withstand significant loads or impacts, for example during transport and installation of the boards. Due to the smaller perforations of the second flange (16), the finishing plaster can adhere to it easily and the construction of the wall or plasterboard can be finished more finely.Therefore, the second flange (16) is also more flexible than the first flange (15), allowing it to adapt to the contours of the wall or plasterboard (24) on which it is to be installed. The fine mesh profile of the second flange (16) also reduces the risk of cracks or crazing in the finish and allows it to be mechanically fixed to the surface to be finished by means of staples, for example, which gives a more durable and aesthetic result.
[0030] In a specific embodiment, the first flange (15) contains, on average over the entire surface area of the flange, no more than 1 gripping opening per cm2, no more than 0.75 gripping openings per cm2, no more than 0.5 gripping openings per cm2 or no more than 0.25 gripping openings per cm2. In another specific embodiment, the size of the gripping openings (21) in the first flange (15) is between 0.5 and 1.5 cm2, between 0.8 and 1.2 cm2, between 0.9 and 1.1 cm2 or is about 1 cm2.
[0031] In another specific embodiment, the second flange (16) comprises, on average over the entire surface of the flange, at least 5 gripping openings per cm2, at least 6 gripping openings per cm2, at least 7 gripping openings per cm2, at least 8 gripping openings per cm2, at least 9 gripping openings per cm2 or at least 10 gripping openings per cm2. In another specific embodiment, the size of the gripping openings (22) in the second flange (16) is between 2 and 15 mm2, between 3 and 12 mm2, between 4 and 10 mm2, between 5 and 8 mm2 or about 6 mm2 or is about 7 mm2.
[0032] The flanges (15, 16) further define a rounded corner edge, so that when the corner profile with the first flange is inserted into the slot of a plasterboard (see below), this corner edge fits the extension of the outer surface of the board. The resulting narrow slot (23) on the outer surface is filled with a putty, so that the outer surface of the element is not embossed and can easily be finished with, for example, paint. The rounded corner edge also provides additional reinforcement, making the corner impact-resistant.
[0033] In a second aspect, the invention relates to a finishing element for a wall portion, more particularly a splay or column side or a wall or ceiling, wherein the element comprises a strip-shaped plate having a slot in one or more longitudinal edges, an accessory as described in the first aspect of the invention, and a glue or other adhesive means by which the accessory is fixed to the plate.
[0034] The aforementioned strip-shaped plate is preferably made of plasterboard, i.e. a plate with a core of plaster or the like and two upper layers of cardboard, since it provides a good support for both tiling and plastering, and also exists in impregnated form, which allows it to be used in damp rooms. Plasterboards can also be easily fixed to the part of the wall to be finished using screws, adhesives and / or adhesive plasters.
[0035] The board is provided with a slot on at least one longitudinal edge, which forms an angle, preferably less than 45°, with the outside of the plasterboard. The slot is preferably made to a depth of 2 to 4 cm in the board with a thickness preferably of 2 to 4 mm, so that the deepest point of the slot is in the center of the board, this slot forming an angle preferably less than 45° with the outside of the plasterboard, so as to preserve as much as possible the compressive strength of the board. Any corner profile described in the first aspect can be fixed in this slot.
[0036] To produce the element with integrated corner profile described here, the corner profile (11) with the first flange (15) is inserted into the slot of the plate (Figures 5-6). This slot is provided with a fastening means for fastening the corner profile in the plate. The aforementioned gripping openings (21) on the first flange (15) ensure a balanced and durable fastening of the corner profile in the plate because, on the one hand, after the adhesive has hardened, a mechanical connection is created in these openings and, on the other hand, the adhesive can spread sufficiently through these openings into the slot. The aforementioned slight curvature at the top of the first flange also contributes to an efficient assembly of the corner profile in the plate, because the hardened adhesive can adhere better due to this difference in relief. This reduces the mobility of the corner profile in the plate, or the risk of the corner profile detaching from the plate.
[0037] In a third aspect, the invention relates to a method of manufacturing said element. According to the invention, the aforementioned element is preferably constructed as a prefabricated element, in which the corner profile is fixed in the plate during manufacture. The manufacture of this element includes the following steps:
[0038] - forming a strip-shaped plate from a plasterboard;
[0039] - making a slot (19) in at least one longitudinal edge (10) of the plate (9);
[0040] - the installation and fixing in this slot (19) with the first flange (15) of a angular profile (11) described in the first aspect of the invention by means of an adhesive; and
[0041] - filling the open joint between the corner profile and the longitudinal edge of the plate using a putty.
[0042] Depending on the application, plasterboards can be manufactured in different dimensions.
[0043] The slot is preferably made in the plate by milling, so as to obtain a uniform slot. A slot can also be made on several longitudinal edges, for example in the case of a four-sided column cladding. In this case, the two longitudinal edges of the plate are provided with a slot into which an adhesive and an angle profile are inserted. The element can thus be applied to the two opposite sides of the column, after which the other sides can be finished with a conventional coating.
[0044] When the corner profile with the first flange is inserted into the slot of the plate, the corner edge fits the extension of the outer surface of the plate. The narrow slot thus created on the outer surface is filled with a sealant, so that the outer surface of the element is not embossed and can easily be painted, for example.
[0045] In a fourth aspect, the invention relates to a method of finishing a splay, a column, a wall or a ceiling, using one of the elements with integrated angle profile described herein. This method comprises the following steps:
[0046] - resizing an element with an integrated corner profile, as described in the second aspect of the invention;
[0047] - fix the element to the splay or to the unfinished part of the wall, for example using screws or glue and / or adhesive coating;
[0048] - finishing at least part of the side of the wall to which the corner profile is fixed, in using the corner profile as a guide for finishing.
[0049] In a particular embodiment, the element is fixed to the unfinished splay or to the part of the wall using screws and / or glue and / or adhesive plaster.
[0050] In another specific embodiment, glue and / or adhesive coating are applied to the unfinished splay or wall portion and / or the element, after which the element is pressed and positioned against the unfinished splay or wall portion. finished. When the glue and / or adhesive coating have sufficiently cured, the assembly can be finished using the method described above.
[0051] In another specific embodiment, the second flange (16) of the element connects to a wall and the assembly is covered with a thin coating. The term "thin coating", as used herein, refers to a form of sprayable coating which is particularly well suited for use in new construction.
[0052] "Plastering" is a plaster whose average thickness is generally around 10 mm. Plastering is generally applied as a classic interior coating on common masonry, concrete blocks, building bricks, etc.
[0053] In another specific embodiment, the second flange (16) connects to a wall constructed or composed of plasterboard and the assembly is finished with a traditional finish characteristic of plasterboard. Here, no thin plaster is used but mastic coatings applied as a filling or jointing layer and / or as a finishing layer.
[0054] Due to the free gripping openings and the slight curvature of the edge of the second flange, a robust connection is created between the element on the one hand and the finish on the other hand after the finishing layers have been spread and hardened on the aforementioned second flange (16) of the integrated corner profile.
[0055] The flat edge of the profile allows for easy and quick installation of the finishing layers. In addition, thanks to the design of the corner profile described here, it is sufficient to apply only 3 mm of finishing to the board or wall connected to the second flange (16) of the corner profile. In the case where the wall to which the second flange is connected is made of plasterboard, it is even sufficient to apply the finishing layer to only a part of the wall to be finished to obtain a perfectly finished assembly. Indeed, the very small difference in thickness is not visually perceptible because the finishing layer is applied over a width of + / - 35 cm with a decreasing thickness over this width. In a specific embodiment, the finishing layer only needs to be applied over a width of approximately 10 cm, approximately 20 cm, approximately 28 cm, approximately 35 cm or approximately 45 cm from the corner profile.In another specific embodiment, the finishing layer only needs to be applied over a width of between 10 and 60 cm, between 15 and 55 cm, between 20 and 50 cm, between 25 and 45 cm or between 30 and 40 cm calculated or measured from the corner profile. This is in contrast to the prior art, where after installing a plasterboard with an integrated corner profile, a 7 mm thick layer of plaster needs to be applied to the entire wall that connects to the second flange (16) and is not compatible with finishing a wall made of plasterboard.
[0056] The present invention will be described in more detail below, with reference to non-limiting figures. DESCRIPTION OF FIGURES
[0057] In order to better demonstrate the characteristics of the invention, an embodiment is described below by way of example without any limiting character, with reference to the figures which accompany it, in which:
[0058] - [Fig.l] schematically represents a window in a finishing version of a splay with a traditional splay element.

[0063] - [Fig.7], [Fig.8] and [Fig.9] show how the corner profile is constructed, whose flange (15) which is integrated into the plate has a limited number of large gripping openings (21) necessary for a solid anchoring in the plate, and whose flange (16) is made of a fine mesh having a large number of small gripping openings (22) necessary for a fine and well-adjusted plaster finish;
[0064] - Figures 8A and 8B show the dimensions and location of the openings of gripping (21, 22) in the first (15) and second (16) flanges, respectively;

[0066] - [Fig. 10] shows in detail how the corner profile is integrated into the element of the invention.
[0067] As shown in Figures 1 to 4, a splay 1, i.e. the side surface of a wall 2 around a window 3 or the like, is finished with a splay element 4, by fixing it against the splay, for example using a quantity of adhesive and / or adhesive plaster 5, as shown in Figures 2, 3 and 4. When the glue and / or adhesive plaster 5 has sufficiently hardened, plastering 6 on the side of the wall 7 can begin immediately. The splay element can also be fixed using screws or other fixing methods. The advantage of screws is that it is not necessary to wait until the glue has sufficiently hardened.
[0068] The invention relates to an element 8 with which a wall part, such as a splay 1, can be easily finished during the production of a coating. [Fig.6] illustrates a preferred embodiment of such an element 8.
[0069] This element 8 comprises a strip-shaped plate 9 for covering the wall part to be finished, in which said plate 9, in this case at a longitudinal edge 10, is provided with an accessory for making an angle, which accessory in this case is formed by an angle profile 11 extending in the longitudinal direction of the plate 9.
[0070] As illustrated, the plate 9 preferably comprises a plasterboard, i.e. a plate with a core 12 of plaster or the like and two upper layers 13-14 of cardboard.
[0071] The corner profile 11 is preferably made of metal, more particularly stainless and / or galvanized steel or aluminum. However, according to the invention, it is not excluded to make it of other materials, for example plastic.
[0072] Figures 6, 7, 8 and 9 illustrate a preferred embodiment of a corner profile 11. The corner profile 11 comprises a first flange 15 and a second flange 16.
[0073] The angle profile 11 is fixed in the plate 9 by means of the flange 15 in the plate 9 itself, as shown in Figures 5 and 6.
[0074] The second flange 16 forms a fixing and / or attachment flange which extends at an angle relative to the plate 9 and which serves as a guide and connecting element for the finishing layer.
[0075] In cross-section, the illustrated flanges 15 and 16 preferably extend at an angle not exceeding 90°, as shown in [Fig.9].
[0076] The corner profile 11 has a part 17 defining a corner edge, as shown in Figures 6 to 9, more precisely a part 17 connecting to the extension of the outer surface 18 of the plate 9.
[0077] The part 17 is preferably circular, so as to provide a small rounding at the location of the angle to be made.
[0078] For example, the corner profile 11 is fixed to the plate 9 in the manner illustrated in Figures 5 and 6.
[0079] First, as shown in [Fig. 5], a slot 19 is made in the longitudinal edge 10 of the plate 9, for example by milling. As shown in [Fig. 5], the slot 19 is located in one half of the plasterboard 9, which prevents the corner profile 11 from coming loose.
[0080] Then, the corner profile 11 is precisely inserted into the slot 19 and fixed there by means of an adhesive 20. This adhesive 20 can first be applied in the slot 19, then, before the adhesive 20 hardens, the corner profile 11 is pressed into this slot.
[0081] It should be noted that the inclined insertion of the flange 15, as well as the fact that the slot 19 is made in an inclined manner in the plate 9, contribute to ensuring that the The corner profile 11 is particularly well fixed in the plate 9, even when subjected to a tensile load in the direction in the plane of the plate 9 and perpendicular to the longitudinal edge 10.
[0082] As shown in Figures 7 to 9, the legs 15 and 16 of the corner profile 11 are provided with means allowing better adhesion, on the one hand, to the glue 20 and, on the other hand, to the coating to be produced subsequently, which consist of gripping openings 21 and 22.
[0083] The fastening openings 21 and 22 are preferably uniform openings that are uniformly distributed over the entire length of the legs 15 and 16, so that the fastening points are uniformly distributed. In a preferred embodiment, the number of openings in the legs 15 and 16 is different, more precisely, the leg 15 contains a limited number of large openings 21 and the leg 16 contains a large number of small openings 22. In the case of the flange 15, the openings 21 are dimensioned so that the flow of the adhesive agent is not hindered and a strong bond can take place between the flange 15 and the element. In the case of the flange 16, the openings 22 are small enough to allow a fine (plaster) finish.In a preferred embodiment, the flange 16 comprises a network of fine mesh or micromesh openings forming a flexible assembly that allows the flange 16 to securely adhere to the wall perpendicular to the member. Another advantage is that the fine mesh profile allows the flange 16 to be easily stapled to the wall portion, facilitating installation and finishing and further reducing the thickness of the finish.
[0084] The small open joint between the part 17 and the longitudinal edge 10 of the plate 9 can be filled, if necessary, with a putty 23, as shown in [Fig. 10]. A flexible jointing mortar will preferably be used for this purpose.
[0085] It is noted that the element 8 is preferably constructed as a prefabricated element, more specifically an element which is assembled before being installed against the wall portion to be finished, as described below.
[0086] Although, according to the invention, it is not excluded to produce the element 8 on the construction site, provided that a suitable milling machine or similar machine is available, the prefabricated element will preferably be produced in the factory.
[0087] It should be noted that the elements 8 can be manufactured and marketed in various standard widths, so that if the width is correctly chosen, the element 8 only needs to be cut or trimmed to length.
[0088] The present invention is in no way limited to the embodiments illustrated in the figures, but such an element for finishing a narrow wall part, the method for manufacturing this element and the method for producing a splay covering using this element can be produced in different variants without departing from the scope of the invention.
[0089] EXAMPLE
[0090] The invention will now be explained in more detail with the aid of the following example, without however being limited thereto.
[0091] Example 1. Finishing of a splay connected to a wall (thin coating)
[0092] For finishing a window splay without sill, when the dimensions of The window opening is 50 cm by 50 cm, four splay elements are supplied with a length of 49 cm. In fact, the plasterboard of these splay elements has a thickness of approximately 1 cm. The four splay elements are cut by the plasterer to a width of 10 cm, corresponding to the depth of the window in the splay.
[0093] It is not strictly necessary for the plasterer to cover the window, as the splay elements facilitate the achievement of a straight finish in the window area, and no finishing is required in the splay portion, thus reducing the time required for finishing.
[0094] The plasterer then applies a first splay element. This can be done using glue and / or adhesive plaster and / or screws. The splay element is placed with one end in a corner of the window opening, so that at the other end of the element there is a 1 cm recess. The plasterer repeats this operation for the other three elements, so that no recess remains and the entire splay is covered.
[0095] Now that the splay elements are in place, the plasterer can complete the transition between the splay elements and the wall perpendicular to the splay. To do this, he uses a thin plaster. Here, the plasterer uses the corner edge of the corner profile as a guide for the plaster, which ensures a flat finish of the plaster. Thanks to the new corner profile described above, which is integrated into the splay elements, it is sufficient to apply a 3 mm thick layer of plaster to achieve a perfect finish ([Fig. 3]). For splay elements with integrated state-of-the-art cutting-edge plaster profiles, a 7 mm layer of plaster must be applied to the entire wall.
[0096] Example 2. Finishing of a reveal connecting to a plasterboard wall.
[0097] The splay element described herein may also, and preferably, be used for finishing a splay when the wall perpendicular to the splay is covered with plasterboard or made of plasterboard ([Fig.4]).
[0098] The splay elements with integrated finishing profile are fixed to the splay using screws and / or adhesive. The fixing flange (16) is then stapled at several points in the plasterboard (24) to which it is connected. Once all the splay elements are in place, the plasterer can begin finishing. Here, the plasterer uses the corner edge of the corner profile as a guide for applying the finishing coat to achieve a flat finish. The finishing plaster is applied with a trowel. This first coat only needs to be applied over a width of 10 to 25 cm, depending on the width of the trowel. After the filler layer has dried, one or more finishing coats are applied. These finishing coats are then reapplied with a trowel, with the thickness of the finishing coat decreasing as you move away from the corner profile. In other words, the finishing coat flattens out and blends into the unfinished plasterboard. The presence of the finishing layer up to 3 mm at the corner profile and its gradual decrease until its absence on the unfinished plasterboard at, for example, 50 cm from the corner profile is no longer visually visible.
[0099] Using the new finishing profile, it is sufficient to apply a filling and / or finishing layer over a width of between 35 and 45 cm to obtain a perfect finish. For splay elements with integrated plaster profiles of the state of the art, a 7 mm layer of plaster must be applied to the entire wall.
